Question

Given `y=(x/5)^2` how do you derive a parametric equation?

Answer 1

The simplest way is to let `x = t`, then `y = (t/5)^2` and the parametric point is `(t,(t/5)^2)`.

Please see the graphs in the explanation.

Explanation:

The following is a graph of the equation `y = (x/5)^2`

The following is a graph of the parametric point `(t,(t/5)^2)`

Please observe that the graphs are identical.
